note: cosmic scale is greater than astronomic scale by scalar multiples of 10^3

Hyper dumbfucks do not belong to the set of dumb nor to dumbfucks. In the set of dumb, you can linearly add the dumb people together and their stupidity will add up proportionally and linearly as well.

however, in Hyper dumbfuck's set, the addition is not linear therefore, they require their own set:

1 hyper dumbfuckism + 2 hyper dumbfuckism = Cosmic scale catastrophe

e.g. If leaders of the world, all belong to set of Hyper dumbfucks, the consequences of their actions will cause catastrophe and total annihilation of everything living on the surface of the planet earth and potential future organisms within this portion of the Milkyway Galaxy.

note: a super nova explosion belongs to the class of cosmic catastrophe
